RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 13/154,876, filed Jun. 7, 2011, entitled “Flexible Display Extendable Assembly,” the entire disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

Portable electronic devices, such as mobile phones, media players, and tablet computers are increasingly common. These types of devices typically include an integrated display device, and many include dual displays. For example, a mobile device can be hinged to open two display devices side-by-side to form one larger display. Users typically want the smallest possible devices to conveniently carry in a pocket or purse, but also want devices with larger display surfaces for easier viewing. Display manufacturers are beginning to develop flexible displays that may be used to provide a larger display surface than would be typically integrated in a smaller, portable electronic device. However, flexible displays are susceptible to damage from environmental factors and when folded, such as in a hinged mobile device that would typically integrate two display devices side-by-side to form the one larger display.

SUMMARY

This Summary introduces simplified concepts of a flexible display extendable assembly, and the concepts are further described below in the Detailed Description and/or shown in the Figures. This Summary should not be considered to describe essential features of the claimed subject matter, nor used to determine or limit the scope of the claimed subject matter.

A flexible display extendable assembly is described. In embodiments, the extendable assembly includes a slideable display guide integrated in a first housing part of an extendable electronic device. The extendable electronic device includes a flexible display that slide-engages into the first housing part of the extendable electronic device. The extendable assembly includes an extendable mechanism that is coupled in a second housing part of the extendable electronic device and to the slideable display guide. The first and second housing parts of the extendable electronic device slide-engage relative to each other. The extendable mechanism is implemented to extend as the first and second housing parts slide apart relative to each other, and also to retract as the first and second housing parts slide together relative to each other.

In other embodiments, a section of the flexible display extends from the first housing part of the extendable electronic device when the first and second housing parts slide apart relative to each other. The section of the flexible display also retracts into the first housing part of the extendable electronic device when the first and second housing parts slide together relative to each other. The extendable mechanism can include one or more extendable scissor mechanisms, or a rack-and-pinion mechanism, that extends in both of the first and second housing parts of the extendable electronic device when the first and second housing parts slide apart relative to each other. The extendable mechanism applies a force to the slideable display guide to extend the section of the flexible display from the first housing part of the extendable electronic device without tension applied to the flexible display. The extendable mechanism also applies a force to the second housing part that pulls the flexible display from the first housing part when the first and second housing parts of the extendable electronic device slide apart relative to each other.

DETAILED DESCRIPTION

A flexible display extendable assembly is described, and embodiments can be implemented for use with a flexible display in a foldable and/or extendable electronic device. For example, a portable device, such as a mobile phone or tablet computer, may be implemented as a foldable and/or extendable electronic device that includes an integrated flexible display. A mobile phone with a flexible display can be used as a standard-size phone and then also extended or unfolded to increase the display viewing surface for a user to read emails, view a map, edit a document, and other tasks that are conveniently accomplished on a larger display.

While features and concepts of a flexible display extendable assembly can be implemented in any number of different devices, systems, and/or configurations, embodiments of a flexible display extendable assembly are described in the context of the following example devices, systems, and methods.

FIG. 1 illustrates examples 100 of a flexible display extendable assembly in accordance with embodiments described herein. An extendable electronic device 102 includes a flexible display 104 and can be implemented with an extendable mechanism 106, shown retracted at 108 and extended at 110. The extendable electronic device is shown in a closed position at 112, and in an open position at 114. The device includes a first housing part 116 and a second housing part 118 that are operable to slide-engage relative to each other. In this example, the second housing part is implemented to slide-engage into the first housing part.

The flexible display 104 may be implemented as a flexible LCD display that is illuminated with a backlight. A flexible backlight 120 can be implemented to illuminate the flexible display, and the flexible backlight extends from and retracts into the first housing part of the extendable electronic device under the flexible display. Alternately, the flexible display may be implemented as a flexible OLED display that self-emits without the need for an integrated flexible backlight.

The extendable electronic device 102 is also shown in the closed position at 122, and the flexible display 104 extends from and retracts into the first housing part 116 of the extendable electronic device. The flexible display is connected to a slideable display guide 124 that is integrated in the first housing part of the device. The extendable electronic device 102 is also shown in the open position at 126, with the second housing part 118 slide-extended from the first housing part 116. The extendable mechanism 106 is coupled to the slideable display guide 124 and in the second housing part 118 of the extendable electronic device. The extendable mechanism is implemented to extend as the first and second housing parts slide apart relative to each other, as shown extended at 110. The extendable mechanism is also implemented to retract as the first and second housing parts slide together relative to each other, as shown at 108.

In embodiments, a section of the flexible display 104 is retractable to slide-engage into the first housing part 116 of the extendable electronic device 102 when the section of the flexible display is not activated for display, such as in the closed position of the device shown at 122. The section of the flexible display extends from the first housing part of the extendable electronic device when the first and second housing parts slide apart relative to each other as shown at 126 (i.e., in the open position of the device). The section of the flexible display also retracts into the first housing part of the extendable electronic device when the first and second housing parts slide together relative to each other as shown at 122 (i.e., in the closed position of the device).

In embodiments, the extendable mechanism 106 is implemented to apply a force 128 to the slideable display guide 124 to extend the flexible display from the first housing part 116 of the extendable electronic device 102 without tension applied to the flexible display. The extendable mechanism also applies an additional force 130 to the second housing part that pulls the flexible display from the first housing part when the first and second housing parts of the extendable electronic device slide apart relative to each other. In this example, the extendable mechanism is an extendable scissor mechanism that extends in both of the first and second housing parts of the extendable electronic device. In other embodiments, the extendable mechanism can be implemented as multiple extendable scissor mechanisms as described with reference to FIGS. 2 and 3, or as a rack-and-pinion mechanism that is described with reference to FIG. 4.

FIG. 2 further illustrates examples 200 of the flexible display extendable assembly implemented in the extendable electronic device 102 described with reference to FIG. 1. In a first configuration at 202, the extendable electronic device includes a single extendable mechanism, such as the extendable mechanism 106. In a second configuration at 204, the extendable electronic device includes multiple extendable mechanisms 206 and 208 that are implemented to extend as the first housing part 116 and the second housing part 118 slide apart relative to each other, and retract as the first and second housing parts of the device slide together relative to each other. In other embodiments, the extendable electronic device can be implemented with multiple extendable scissor mechanisms as described with reference to FIG. 3, or with a rack-and-pinion mechanism as described with reference to FIG. 4.

FIG. 3 further illustrates examples 300 of a flexible display extendable assembly, such as may be implemented in the extendable electronic device 102 shown in FIG. 1. In a first configuration, an extendable mechanism 302 includes multiple extendable scissor mechanisms that extend as the first and second housing parts of an extendable electronic device slide apart relative to each other, and retract as the first and second housing parts of the device slide together relative to each other. In a second configuration, an extendable mechanism 304 includes integrated extendable scissor mechanisms that extend as the first and second housing parts of an extendable electronic device slide apart relative to each other, and retract as the first and second housing parts of the device slide together relative to each other.

FIG. 4 illustrates examples 400 of a flexible display extendable assembly, such as may be implemented in the extendable electronic device 102 shown in FIG. 1. In this example, an extendable electronic device 402 includes a flexible display 404 and an extendable rack-and-pinion mechanism 406, shown retracted in a closed position of the extendable electronic device at 408 and shown extended in an open position of the device at 410. The extendable rack-and-pinion mechanism 406 is also shown from a top view at 412.

The extendable electronic device 402 includes a first housing part 414 and a second housing part 416 that are operable to slide-engage relative to each other. In this example, the second housing part is implemented to slide-engage into the first housing part. The extendable rack-and-pinion mechanism 406 extends as the first and second housing parts of the extendable electronic device slide apart relative to each other, and retracts as the first and second housing parts of the device slide together relative to each other.

The flexible display 404 extends from and retracts into the first housing part 414 of the extendable electronic device. The flexible display 404 may be implemented as a flexible LCD display that is illuminated with a backlight. A flexible backlight 418 can be implemented to illuminate the flexible display, and the flexible backlight extends from and retracts into the first housing part of the extendable electronic device under the flexible display. Alternately, the flexible display may be implemented as a flexible OLED display that self-emits without the need for an integrated flexible backlight.

FIG. 5 illustrates example method(s) 500 of a flexible display extendable assembly. The order in which the method blocks are described are not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement a method, or an alternate method.

At block 502, a first housing part of an extendable electronic device is slide-engaged relative to a second housing part of the extendable electronic device that includes a flexible display. For example, the extendable electronic device 102 (FIG. 1) includes the first housing part 116 and the second housing part 118 that slide-engage relative to each other. The extendable electronic device also includes the flexible display 104 that may be implemented as a flexible LCD display, or as a flexible OLED display.

At block 504, an extendable mechanism is extended as the first and second housing parts of the extendable electronic device slide apart relative to each other. For example, the extendable electronic device 102 includes the extendable mechanism 106, which extends as the first and second housing parts of the device slide apart relative to each other, as shown extended at 110.

At block 506, a section of the flexible display extends from the first housing part of the extendable electronic device when the first and second housing parts slide apart relative to each other. For example, the section of the flexible display 104 extends from the first housing part 116 of the extendable electronic device 102 when the first and second housing parts slide apart relative to each other as shown at 126 (i.e., in the open position of the device).

At block 508, a first force is applied to a slideable display guide with the extendable mechanism to extend the flexible display from the first housing part without tension applied to the flexible display. For example, the extendable mechanism 106 applies the force 128 to the slideable display guide 124 to extend the flexible display 104 from the first housing part 116 of the extendable electronic device 102 without tension applied to the flexible display.

At block 510, a second force is applied to the second housing part with the extendable mechanism to pull the flexible display from the first housing part of the extendable electronic device. For example, the extendable mechanism 106 also applies the additional force 130 to the second housing part 118 that pulls the flexible display 104 from the first housing part 116 when the first and second housing parts of the extendable electronic device 102 slide apart relative to each other.

At block 512, the extendable mechanism is retracted as the first and second housing parts of the extendable electronic device slide together relative to each other. For example, the extendable mechanism 106 retracts as the first and second housing parts of the extendable electronic device 102 slide together relative to each other, as shown at 108.

At block 514, the section of the flexible display is retracted into the first housing part of the extendable electronic device when the first and second housing parts slide together relative to each other. For example, a section of the flexible display 104 is retractable to slide-engage into the first housing part 116 of the extendable electronic device 102 when the section of the flexible display is not activated for display, such as in the closed position of the device shown at 122. The section of the flexible display retracts into the first housing part of the extendable electronic device when the first and second housing parts slide together relative to each other as shown at 122 (i.e., in the closed position of the device).

At block 516, the flexible display is illuminated with a flexible backlight that extends from and retracts into the first housing part of the extendable electronic device under the flexible display. For example, the flexible backlight 120 illuminates the flexible display 104, such as a flexible LCD display, and the flexible backlight extends from and retracts into the first housing part of the extendable electronic device under the flexible display.
